If you own a Gazell method harmonica and want to learn how to play it at your own pace, then you should check out my two online courses at Music Gurus. There is an introductory course to half valving and a more advanced course which shows you how to start integrating the valved bends into your playing. The introductory course has 8 lessons and the more advanced course has 10. Both courses feature numerous PDF's that you can download with tips and exercises as well as a few songs to get you moving in the right direction. Best part is that this is a one time fee per course and you can revisit it as many times as you like.
